East Antarctic Melting Could Raise Sea Levels By 10 To 13 Feet, Study Finds
2014-05-05 08:27:00| Climate Ark Climate Change & Global Warming Newsfeed
ThinkProgress: A region of East Antarctica is more vulnerable than previously thought to a massive thaw that could result in world sea levels rising for thousands of years, a study found Sunday. The study, published in the journal Nature Climate Change, looked at the 600-mile Wilkes Basin in East Antarctica, which, if it melted, has enough ice to raise sea levels by 10 to 13 feet. Researchers found that the region was vulnerable to melting because it`s held in place by a small "ice plug" that may melt over the...
Scientists warn that newly discovered Greenland melting could accelerate sea-level rise
2014-03-17 06:00:00| Climate Ark Climate Change & Global Warming Newsfeed
ClimateWire: A large area of the Greenland ice sheet once considered stable is actually shedding massive amounts of ice, suggesting that future sea-level rise may be worse than expected, a team of scientists warned yesterday in a new study. Regional warming has triggered newly discovered ice melting in a large portion of northeastern Greenland. The area, marked NEGIS, covers about 16 percent of the island's thick ice sheet.

With ice melting, U.S. pushes for limits on fishing in Arctic Ocean
2014-02-22 17:30:00| Climate Ark Climate Change & Global Warming Newsfeed
LA Times: U.S. officials are heading to Greenland for a three-day meeting to persuade other Arctic nations to place a moratorium on high-seas fishing in the Arctic Ocean, where climate change is melting the permanent ice cap and allowing trawlers in for the first time in human history. The United States is proposing an agreement "that would close the international waters of the Arctic Ocean to commercial fishing until there is a good scientific foundation on which to base management of any potential fishing,'...

Melting of Antarcticas Pine Island glacier may continue for centuries
2014-02-21 17:24:00| Climate Ark Climate Change & Global Warming Newsfeed
Blue and Green: The rapidly melting Pine Island glacier in West Antarctica may be the biggest contributor to rising sea levels over the next few decades, a new study has suggested. The research, published in the journal Science, found that the largest glacier in Antarctica may be recreating 8,000-year-old history. Scientists from the US, UK and Germany found that the glacier also thinned in the Early Holocene, in a melt that may have lasted for centuries. The Pine Island glacier has currently been thinning...

Warming from Arctic Sea Ice Melting More Dramatic than Thought
2014-02-17 21:25:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: Melting Arctic sea ice has contributed considerably more to warming at the top of the world than previously predicted by climate models, according to a new analysis of 30 years of satellite observations. Sea ice helps cool the Arctic by reflecting incoming solar radiation back into space. Because of its light color, sea ice has what is known as high albedo, which is the percentage of solar radiation a surface reflects back to space. Dark ocean water left behind by melting sea ice, on the other...
